In the high heavens above Midgard, two colossal wolves sprint endlessly across the sky. One pursues Sól, the goddess driving the fiery chariot of the sun; the other stalks her brother Máni, who guides the light of the moon. Their heavy footfalls echo through the clouds, and their snapping jaws draw closer with every passing season.
Their names are Sköll and Hati—the celestial predators of Norse mythology.
Unlike other prominent beasts in Scandinavian lore—such as the World Serpent Jörmungandr or the monstrous wolf Fenrir—Sköll and Hati engage in no epic duels with mortal heroes, nor do they strike bargains with the Aesir gods. Their singular, ominous role is built directly into the fabric of time itself: to hunt down the heavenly bodies and devour them, plunging the cosmos into pitch darkness to trigger Ragnarök, the twilight of the gods.
In this deep dive into medieval Scandinavian mythology, we will examine the primary Eddic sources preserving these wolves, trace their origins to the mysterious Ironwood, analyze their complex family lineage, untangle overlapping identities like Mánagarmr, and discover how their cosmic chase reflects a world built upon cycles of destruction and rebirth.
1. Etymology and Identity: Mockery and Hatred
To understand the nature of these celestial hunters, we must turn to the Old Norse language. Their names were chosen with explicit intent, embodying hostile cosmic forces:
+-------------------------------------------------------------------------+
| ETYMOLOGY OF THE CELESTIAL WOLVES |
| |
| [ SKÖLL ] ---> Old Norse *Sköll*: "Mockery", "Scoffing", or |
| "Threatening Noise". (The Sun-Hunter) |
| |
| [ HATI ] ---> Old Norse *Hati*: "Hater", "Enemy", or |
| "Despiser". Full patronymic: *Hati Hróðvitnisson*. |
| (The Moon-Hunter) |
+-------------------------------------------------------------------------+
- Sköll: Derived from Old Norse root words connected to mockery, noise, or deception. Sköll is the wolf designated to hunt the sun. (Note: This is distinct from the Scandinavian toast skál, meaning "drinking vessel" or "cheers!").
- Hati: Translates directly to "Hater" or "The One Who Hates." His formal patronymic title, Hati Hróðvitnisson, explicitly identifies him as the son of Hróðvitnir ("The Famous Wolf")—a well-established kenning for Fenrir.

2. The Celestial Prey: The Chariots of Sól and Máni
To understand why the wolves hunt, one must understand how medieval Scandinavians conceptualized the sky. In the Prose Edda (Gylfaginning, Chapter 11), Snorri Sturluson explains that the sun and moon are not inanimate rocks or floating fireballs, but living divine beings.
THE COSMIC CELESTIAL RACE
[ Múspellheim Sparks ] ---> Forged into Sól's Sun Chariot
|
[ Horses ] ---> Árvakr ("Early Awake") & Alsviðr ("All-Swift")
|
[ Chasing Wolf ] ---> SKÖLL (Closing in from behind)
A mortal man named Mundilfari had two exceptionally beautiful children. Out of pride, he named his daughter Sól ("Sun") and his son Máni ("Moon"). Offended by his arrogance, the Aesir gods pulled the siblings up into the sky to steer the movements of the heavens:
-
Sól’s Chariot: Sól drives the golden chariot carrying the sun, forged from sparks of Muspelheim. Her chariot is pulled by two legendary horses: Árvakr ("Early Awake") and Alsviðr ("All-Swift"). To protect the horses and Sól from incinerating under the sun's intense heat, the gods placed a magical shield named Svalinn ("Cooler") in front of the wagon.
-
Máni’s Duty: Máni controls the movement and shifting phases of the moon. He is accompanied by two human children, Bil and Hjúki, whom he plucked from Earth while they were carrying a bucket of water from a sacred well.
When asked why Sól drives her chariot at such breakneck speed across the sky, the god Hárr explains in Gylfaginning Chapter 12:
"It is no wonder she moves so fast: the one who seeks her is close behind her, and she has no way out except to run."
3. Literary Primary Sources: Poetic Edda and Prose Edda
Our knowledge of Sköll and Hati rests upon core medieval Icelandic manuscripts: the Poetic Edda (compiling older pagan oral traditions) and Snorri Sturluson’s 13th-century Prose Edda.
PRIMARY LITERARY SOURCES
|
+----------------------------------+----------------------------------+
| | |
Grímnismál (Poetic Edda) Gylfaginning (Prose Edda) Völuspá (Poetic Edda)
* Stanza 39 names both wolves * Chapter 12 details the chase * Stanza 40 details Ironwood
* Identifies Hati as Fenrir's son * Explains Sól & Máni's panic * Foretells swallowing of light
1. The Poetic Edda: Grímnismál (Stanza 39)
The oldest direct poetic mention of the pair appears in Grímnismál ("The Lay of Grimnir"):
"Sköll heitir úlfr, er fylgir inum skírleita goði
til skógar hlés;
en annarr Hati, hann er Hróðvitnis sonr,
sá skal fyr heiða brúði hira."
(Sköll is the wolf who follows the shining god
to the protective woods;
and another is Hati, he is Hróðvitnir’s son,
who runs ahead of the bright bride of heaven.)
2. The Prose Edda: Gylfaginning (Chapter 12)
Snorri Sturluson clarifies the poetic ambiguity of Grímnismál, establishing a clear narrative breakdown:
"There are two wolves, and the one that runs after her is called Sköll; she fears him and he will catch her, but the one that leaps before her is named Hati Hróðvitnisson, and he wants to catch the moon."
To compare how Old Norse texts categorize these celestial predators, let us examine a comparison table detailing their targets, lineage, and cosmic fates.
| Wolf Identity | Primary Target | Known Parentage | Alternate Names / Designations | Role at Ragnarök |
| Sköll | The Sun (Sól) | Descendant of Fenrir & Ironwood Giantess | Sköl ("Mockery / Noise") | Catches and devours the sun's chariot |
| Hati | The Moon (Máni) | Fenrir (Hróðvitnir) & Ironwood Giantess | Hati Hróðvitnisson ("The Hater") | Swallows the moon and spatters sky with blood |
| Mánagarmr | Celestial Bodies / Dying Souls | Ironwood Wolf Clan | "Moon-Hound" / "Dog of the Moon" | Devours the flesh of the dead; darkens stars |
4. The Ironwood and the Lineage of Fenrir
Where did these monstrous wolves come from? Old Norse sources point to a sinister, isolated realm located east of Midgard: Járnviðr ("The Ironwood").
+-------------------------------------------------------------------------+
| THE MONSTROUS LINEAGE OF IRONWOOD |
| |
| [ LOKI ] + [ ANGRBOÐA ] |
| | |
| [ FENRIR THE WOLF ] + [ IRONWOOD GIANTESS ] |
| | |
| +---------------+---------------+ |
| | | |
| [ SKÖLL ] [ HATI ] |
+-------------------------------------------------------------------------+
According to stanza 40 of Völuspá ("Prophecy of the Seeress"), an ancient giantess sits within the dark iron-leafed forest of Járnviðr, breeding the monstrous brood of Fenrir:
"East sat the old one in Ironwood,
and bred there the brood of Fenrir;
there comes from them all one in particular,
the snatcher of the moon in troll's shape."
Was the Mother Angrboða?
In popular Viking culture, it is often asserted that the giantess of Ironwood was Angrboða—the witch-mother who bore Fenrir, Jörmungandr, and Hel with Loki.
However, primary Eddic texts do not explicitly state her name in the Ironwood passages. While it is historically plausible that Angrboða either mothered or grandmothered this wolf clan, scholarly accuracy requires acknowledging that the texts leave her exact name unstated, referring to her simply as the gýgr (ogress/giantess) of Ironwood.
5. The Mánagarmr Identity Debate
A common source of confusion in Norse mythology involves another monstrous wolf mentioned by Snorri: Mánagarmr ("Moon-Hound").
Mánagarmr ("Moon-Hound").
In Gylfaginning, Snorri writes:
"He is filled with the life-force of all those people who die, and he will swallow the moon and spatter heaven and all the sky with blood."
THE MÁNAGARMR QUESTION: ONE WOLF OR TWO?
|
+-------------------------------+-------------------------------+
| |
Hypothesis A: Mánagarmr = Hati Hypothesis B: Distinct Figures
* Both are wolf descendants of Fenrir * Hati pursues the moon in daily sky
* Both are foretold to devour the moon * Mánagarmr is a separate corpse-eater
* "Mánagarmr" may be an epithet or title * Reflects overlapping oral traditions
Is Mánagarmr simply a descriptive title for Hati, or is he a third, distinct wolf?
Because Hati means "Hater" and Mánagarmr means "Moon-Hound," many runologists and mythologists argue they are identical figures—with "Moon-Hound" serving as an epithet for Hati. However, because medieval oral tradition preserved variant regional tales, it is equally possible that different Norse communities held distinct stories about which wolf would deal the killing blow to the moon.
6. Ragnarök: The Culmination of the Chase
The end of the celestial pursuit marks the beginning of Ragnarök. For centuries, the gods maintained order, but the prophecies recorded in Völuspá and Gylfaginning make clear that the wolves will eventually prevail.
+-------------------------------------------------------------------------+
| THE SEQUENCE OF CELESTIAL COLLAPSE |
| |
| 1. FIMBULVETR: Three consecutive severe winters without summer. |
| 2. THE CATCH: Sköll devours Sól; Hati swallows Máni. |
| 3. COSMIC DARKNESS: Stars vanish, skies spatter with blood. |
| 4. BONDS BREAK: Earthquakes shatter fetters; Fenrir goes free. |
+-------------------------------------------------------------------------+
Did Fenrir or Sköll Swallow the Sun?
Intriguingly, the Poetic Edda preserves a slight variation regarding who devours the sun. While Snorri’s Prose Edda attributes the capture of Sól to Sköll, the poem Vafþrúðnismál (stanza 46) states that Fenrir himself will swallow the sun:
"A daughter shall Sól bear before Fenrir catches her;
she shall ride, when the gods die,
along her mother's ancient path."
Did Fenrir or Sköll Swallow the Sun?
This variation does not mean one source is "wrong." Rather, it illustrates how Norse mythology functioned as an evolving oral tradition where Fenrir and his wolf offspring (Sköll, Hati, and Mánagarmr) were deeply intertwined in the cosmic destruction of light.
7. Hope After Darkness: Sól’s Daughter and Cosmic Rebirth
Despite the grim nature of the celestial hunt, Norse mythology is not a philosophy of absolute annihilation. It is a story of cyclical transformation.
As revealed in Vafþrúðnismál stanza 47, before Sól is devoured by the wolf, she gives birth to a daughter. Following the cataclysm of Ragnarök—after the sea recedes, the earth rises green and beautiful from the waters, and the surviving gods gather at Iðavöllr—this daughter steps into her mother's footsteps.
THE CYCLE OF DESTRUCTION AND RENEWAL
|
Old World (Sól & Máni) ===> Ragnarök (Sköll & Hati) ===> New World (Sól's Daughter)
Driven by fear & pursuit Light devoured by wolves New sun warms reborn earth
The new sun drives her chariot across a cleansed sky, completely unburdened by monstrous pursuers. The death of the old sun gives birth to a renewed cosmic order, proving that even the ultimate triumph of Sköll and Hati cannot extinguish light permanently.

8. Real-World Connections: Eclipses and Sun Dogs
Why did ancient Scandinavians conceive of celestial wolves hunting the sun and moon? Modern researchers look to both folklore and real-world atmospheric phenomena across the Northern sky.
+-------------------------------------------------------------------------+
| ATMOSPHERIC & FOLKLORIC PARALLELS |
| |
| * SOLAR & LUNAR ECLIPSES: Darkening of celestial bodies interpreted |
| as temporary attacks by cosmic predators. |
| * SUN DOGS (Parhelia): Optical ice crystal reflections flanking the |
| sun, creating the visual illusion of wolves running beside it. |
+-------------------------------------------------------------------------+
Solar and Lunar Eclipses
While modern readers often assume Vikings believed every eclipse meant Sköll or Hati was attempting to swallow the sun or moon, the Eddic texts do not explicitly state that eclipses are temporary near-captures.
However, comparative mythologists note that cultures worldwide—from Hindu traditions of Rāhu to Chinese folklore of the Tiāngǒu celestial dog—interpreted eclipses as warnings from divine beasts attempting to devour heavenly light.
Sun Dogs (Parhelia)
In cold Northern latitudes, sunlight refractions through ice crystals in the atmosphere create sun dogs (parhelia)—bright spots of light that flank the sun on either side. To an ancient Scandinavian observer, these luminous companions appearing on the horizon visually resembled two bright wolves running alongside the sun's chariot.
The Timeless Resonance of the Celestial Hunt
Exploring the myth of Sköll and Hati reveals one of the most compelling narratives in ancient Scandinavian lore. Far more than simple monsters, these celestial wolves embodied the inevitable passage of time, the precarious nature of light in the frozen North, and the deep Norse belief that all creation moves toward a foretold transformation.
Though the wolves still run across the sky and the darkness of winter presses in, the promise of the skalds remains unbroken: after every night comes the dawn, carrying forward the great tales of valhalla.
